Wax emulsions can effectively improve the surface properties of the coating, mainly including improving the smoothness of the coating, scratch resistance, improving water resistance, changing the rheological properties of the coating, and matting agent. 1, Anti-slip, anti-adhesion, stain resistance: how wax migrates to the surface in the coating, which is related to the wax and coating to interaction, drying form, thickness of the film, strength of the wax, dispersion state and density of the wax. 2, Abrasion and scratch resistance: wax emulsion added to the paint can make the coating reduce the tendency of being polished by friction, while maintaining the durability of low gloss. 3, Matting agent: different particle sizes and varieties of wax emulsions, the matting effect varies greatly, from completely maintaining the gloss to deep matting. The intensity of matting of the coating surface can be controlled by adding wax molecules of different particle sizes and amounts. 4, Feel and appearance effect: wax additives can effectively improve the feel of the coating surface, so that the coating has a good sense of wax as well as a silky feel. Will make the surface of the coating film has a very unique visual effect, usually people call it wax sense. About the water-based wax emulsion particle sizes, usually small particle size, the gloss improvement is obvious, large particle size, the anti-wear improvement is obvious. Whether it is architectural and industrial coatings, the use of similar methods, but the process will have some differences.
